Hirsute: Install the Hirsute on that Dell machine (sdw audio without headset), enable the hirsute-proposed ppa in the /etc/apt/sources.list, sudo apt- get update, sudo apt install libasound2, the libaousnd2 1.2.4-1.1ubuntu2.1 is installed, reboot, check the gnome-sound-setting, the speaker and internal digital mic show in the UI, this means the pulseaudio loads the correct UCM for this machine. And test playback and recording, all worked well.

But on this machine, the ucm can't be loaded, through debugging, we found this machine has no headset, the Regex returns a wrong value when matching "Regex " hs:([a-z0-9]+(-sdca)?)". If let Regex returns a correct value, the ucm could be loaded successfully. [Fix] Backport a commit from upstream, this commit is merged to upstream from v1.2.5 [Test] After installed the patched libasound2, reboot, we could see the ucm is loaded succesfully on this machine, and open the gnome-sound-setting, we could see the internal mic and internal speaker, and all of them could work normally. [Where problems will occur] This change affect the Regex parser in the ucm, so if it could introduce regression, it will be on the ucm. It could make the audio not work (fail to load ucm and users can't see any audio devices from gnome) on the machines which need ucm. But this possibility is very low, since this commit is backported from upstream and we already tested this backporting on 2 lenovo machines and 2 Dell machines which all need ucm to work.
